We know that slope represents rate of change of function.
We will use slope formula to solve our given problem.
Let and
.
Therefore, the rate of change of the given function is .
The maximum units is 200 and , Total revenue is $8,000
<u>Step-by-step explanation:</u>
Here we have , A manufacturer finds that the revenue generated by selling of cortan commodity is given by function R(x)=80x-0.2x^ 2 , where he maximum reveremany should be manufactured to obtain this maximum units .Let's find out:
We have following function as . Let's differentiate this and equate it to zero to find value of x for which the function is maximum!
